dhcpcd: log basic send and receive at INFO level

When we send or receive a DHCP packet, log the type and the
transaction ID at level LOG_INFO. This will help to diagnose
problems in the field, and in the lab.

BUG=chromium:291284
TEST=network_DhcpNegotiationSuccess, manual

Manual test:
- ran the autotest
- ran egrep 'dhcpcd.+(sending|received) DHCP' /var/log/net.log on the DUT
- saw matching lines
